Question

What $pH$ is associated with a neutral solution?

• A. $9$
• B. $7$
• C. $0$
• D. $14$

Answer 1

The correct option is B $7$

The pH of a neutral solution is 7.
At this pH, the solution has equal concentrations of both the $H^{+}$ and $O{H}^{-}$ ions, which is ${10}^{-7}$ mole/litre. The presence of both the hydrogen and hydroxyl ions in equimolar concentrations makes the solution neutral.
